1 Claim.

tory ailments, in which the medicament is applied in the form of a vapor by compressed air, and also in which the temperature of the medicament is raised, which is of special value in bronchial ailments, by preheating the air, and in which vaporization is obtained by applying the heated air under pressure tothe medicament in a nebulizer.

The invention is a mask or other applicator connected by a tube to a nebulizer, in which the medicament is contained, and air is suppplied to the nebulizer, as desired, under pressure from a motor driven rotary compressor, and the air is passed through a heating chamber for raising the temperature thereof. The medicament may also be applied by directly passing the air under pressure through a chamber in which the medicament may be contained in spongelike particles;

and the device may also be used for withdrawing pus, and the like, as from tonsils, by connecting the air tube to the suction terminal of the compressor.

Similar devices have been provided, and some operate in a similar manner, but it has been found impossible toproperly vaporize the medicament,

and the application is far more efficient with the medicament properly vaporized and applied under pressure. Some devices apply heat by boiling the liquid, others apply the liquid cold or at normal temperature, and others use a spray; however, it

has been found desirable to use means for volatilizing the medicament and applying it in the form of vapor, as with themedicament applied in this manner it penetrates the small pores of the sinus tracts, and is far moreefiective.

The object of the invention is, therefore, to provide means in an applicator of this type for readily volatilizing the medicament so that it may be applied in the form of vapor.

Another object is to provide means for vaporizing a medicament in an applicator, in which it may be applied under pressure.

A further object is to provide an applicator having compressed air for applying the medicament, in which the process may be reversed so that the device may be used with suction for withdrawing pus and the like.

And a still further object is to provide an applicator of the type described, which is of a simple and economical construction.

With these ends in view the invention embodies a mask mounted upon a stand and adapted to fit over the nose and mouth, a nebulizer in which the medicament may be contained mounted in a receptacle on said stand, a motor driven rotary compressor used incombination therewith, and suitable tubing connecting the compressor through said'heating element to said nebulizer,

and the nebulizer to said mask. The device also involves the use of a receptacle for containing a medicament which may be directly applied to the compressor for applying the medicament under pressure.

Other features and advantages of the invention .will appear from the following description taken in connectionwith the drawing wherein:

Figure 1 is a view showing a side elevation of the device.

Figure 2 is a view showing an end elevation with parts broken away.

Figure 3 is a sectional plan with the mask omitted.

Figure 4 is a view showing a casing with a motor driven rotary compressor therein.

Figure 5 is a View showing an alternate design in which the applicator may be directly connected to the compressor.

In the drawing the device is shown as it may be made, wherein numeral l indicates the mask, numeral 2, the nebulizer, numeral 3, the heater, and numeral 4, a case in which the compressor and motor may be contained.

The mask l is preferably formed with a soft resilient contact member. 5 which may be placed against the face, and a bowl 6 which is provided with a nipple l to which a tube 8, from the nebulizer 2, may be connected. The nebulizer is connected by a tube 9 which passes through the heating element 3, and this extends to a rotary compressor ID in the case 4, the compressor being operated by a motor I I also in said case, or by any suitable means.

The mask I is supported upon a stand l2, which is attached to a base l3, the nebulizer 2 is freely mounted in a receptacle M on the base, and the heating element 3 is freely mounted between brackets l5 and IE on the same base. An electric any manner. The base [3 may also be provided j with a spring clip 2| for holding the tube 9 at i 3 the corner thereof, as shown in Figure 1. It will, therefore, be understood that, when the motor II is started, air will be supplied from the com- I pressor l0 through the tube 9, to the heating element 3, and from the heating element to the upper part of the nebulizer 2, where it enters 1 through a fitting 22, and is discharged down- 1 ward into the nebulizer through fine openings in the lower part of a member 23, and this air causes a pressure upon the liquid medicament, as indicated by the numeral 24, forcing the medicament up through a glass tube 25 into the connection 26 through which it passes through the tube 8 to lines in Figure 1.

The device may also be provided with an injector as shown in Figure 5, which is formed with a tubular casing 28, and the medicament may be contained in a sponge member 29 in an inner glass tube 30, with the lower'end of the case connectedby a tube 3| to the compressor [0, through a tube similar to'the tube 9, and the upper end may be provided with injectors 32 and 33 which may be inserted in the nostrils and these inthe mask, I, into which it is injected througha relatively small nozzle 21', as indicated in dotted 1, and may be provided with a separate applicator as shown in Figure 5, and these devices may be arranged in any suitable manner.

It is also understood that this device may be used in combination with the applicator shown in Figure 1, in which the tube 3| may be connected to the case shown in Figure 1, which is indicated by the numeral 39, and similar to the case shown Patent, is:

jectors may be mounted ina flexible or resilient tubular member 34 as shown. Thecase 28 may be provided with threaded caps 35 and 36, so that it may be opened, thereby making it possible to remove and replace the sponge element or apply an additional medicinal substance or m d c ment.

It is understood, therefore, that the devic v be'formed of a complete unit, as shown inFig'ur A medicament spraying apparatus comprising a mask adapted to be placed over the nostrils, a platform upon which said mask is mounted, a medicament reservoir mounted on said platform, an air heating device on said platform, a device for supplying air under pressure, a connection fromthe said reservoir to the mask, a nozzle at the mask end of said connection; and air supply connections from the pressure supplying means to the heating device and from the heating device to the reservoir, said connection from the heating device to the reservoir characterized in that it enters the reservoir around the connection from the reservoir to the mask, thereby supplying heat to the medicament'passing through said connection, and also in that itenters the reservoir above the medicament.
